Application filed October 25, 1926.

i a This invention relates to improvements in ditching plows ot the type described and claimed in United States Letters Patent No. 1,311,829 granted to me July 29, 1919.

It isthe object of this invention to produce a ditching plow of the type referred to above which shall be very substantially constructed and which shall be provided with a variety of adjustments whereby it becomes possible to vary the depth and width of the ditch to suit any conditions that might be met with in actual practice. As it is often necessary to run ditches along hillsides, I intend to provide this plow with means which will make it possible to maintain the plow in a substantially horizontal position regardless of the inclination of the ground.

that is being ditched.

The above and other objects which may become apparent as the description proceeds.

are attained by means of a construction and arrangement of parts which will now be described in detail, reference for this purpose being had to the accompanying drawings on which the preferred embodiment of the invention has been illustrated and in which:

Fig. 1 is aplan view 01 the plow, the tongue having been broken away to better disclose the construction;

Fig. 2 is a section taken on line 2-2, Fig. 1;

Fig. 3 is a longitudinal section taken on line 33, Fig. 1; and

Fig. 1.

The plow comprises a curved beam portion 1 whose lower end is secured to the pointed bar 2 by means of rivets 3. Corn bined shares and mold boards 4 are secured to the sides of beam 1 by means otbolts 5. These mold boards extend rearwardly and upwardly with respect to the pointed bar 2 and form an angle with each other in the manner shown quite clearly in the drawing. Transverse brace members 6 and 7 extend between the mold boards 1 and are secured to the latterby means of bolts 8 and 9. The pointed bar 2 extends rearwardly beyond the point of connection to the beam 1 and 18 provided with spaced openings 10 for the reception of bolts or rivets by means of which the channel bar 11 is secured thereto. The bar lltorms a rearward extension otthe pointed. bar 2 and has its rear end secured to the of the upwardly extending DITCHING PLOW.

braces 12 by means of a bolt 13. The upper ends of the bars 12 have been indicated by numeral let and are clamped between the ends 01": the bar 7 and the mold board by means of the bolts 9 in the manner quite clearly shown in Figure 4. The bars 2 and 11 form a runner on which the plow rests when in operative position. A tongue 15 has secured to its rear end a steel clamping bar 16 whose rear end is ofiset and curved in the manner designated by numeral 17. A bar 18 of spring steel has an end portion 19 that is located between the bar 16 and the lower side of the tongue. Bolts 20 extend through the tongue and through the parts 16 and 19, while another bolt 21 extends through the bar 18 the pipe '7 and the curved portion 17, all in the manner shown in Fig. 3. The upper end or the spring 18 has a rearwardly bent portion 22 to which the seat 23 is secured by means of a bolt 24. The upper end of the beam 1 has a fork consisting of two parallel bars 25 and 26, which are arcuate and have their concave sides towards the rear; these parts are curved about the center of pipe 7. The rear concave side of the part 25 is provided with notches 27 with which the reciprocable detent 28 cooperates. Secured to thetongue by means of a bolt 29 is a guide 30. through'which the rearwardly projecting part 31 of the detent 28' extends. A link 32 is pivotally connected at 33 with the detent 28 and has secured to its forward end a coil spring 34 which is under tension and has its'forward end secured to the tongue by means of an eye bolt 35. This spring tends to move the detent forwardly into engagement with the notches 27; A quadrant 36 is secured to the tongue by means of bolts 37. Pivotally attached to the quadrant is a bell crank lever having an upwardly extending handle portion 37 and a forwardly extending part 38. A bolt 39 passes. through the bell crank lever at 'the angular portion thereof and serves as a pivot about which the lever may be rotated. The forward end of the portion 38 is provided with a slot 40 for the reception of a pin- 11 that is secured to the part 25. Pivoted on the bolt 39 is a triangular lever 12 which is provided with openingsttl and 1 1, a link d5. extends from an openin in the part 31 to the opening 4:3 in the lever 42, and a rod 16 extends from the e ning 1 k handle portion 17 whieh pivoted at 18. Another rod 4-9 extends from the handle portion 1-7 to a suitable detent 50 which cooperates with the notches 51 in the quadrant 36. lVhen the operator grasps the handle 37 and moves the handle portion 47 about its pivot 48, he releases the detent 50 and the detent 28, and therefore when the handle 37 is rocked about its pivot 89, the beam 1 can be raised and lowered with respect to the tongue 15. VI hen the parts have been moved to the desired position, pressure on the bandle portion 4-7 is relieved and this permits the detents 28 and 50 to engage with the notches 2? and 51 so as to hold the parts in adjusted position.

In order to hold the plow steady, and to incline it to the desired extent with respect to the surface of the ground, I have secured :to the pipe 7 two bearing members 52 and 53. These members are held against rotation with respect to pipe 7 by means of bolts '54 which pass "through the pipe 7. Bearing members 52 and 53 are also provided with openings for the reception of the shaft One end of shaft 56 has a rea-rwardly extending arm 57 whose rear end is forked and provided with openings for the pivot pin 58. A tori; has an upwardlv extending portion 60 which extends between the two parts of the forked portion of the arm 57 and is pivotally connected therewith by .means' of the bolt 58. l Vheel 61 is pivoted to the rtorl: '59 and rotates about the axis of ,the bolt 62. The bearing 53 is provided with a ratchet which is termed integral there with. and has its arcnate edge provided with a plurality of ratchet teeth '64.

A h and lie 65 is secured to the shaft 56 between the arm -51 and the bearing 53 and is held against .portion Fig. 1. By moving the handle portion 70, the detent 68 may be moved into and out of operative relation with the notches 64:. It is now evident that by means of the lever 65 the shaft 56 may be rotated and in this nanner the wheel 61 may be raised or lowered with respect to the runner 11. Secured to the other end of shaft 56 is a quadrant 71 which is held against rotation on the shaft by means of the pin 7 2, Fi 2. This quadrant is provided with teeth 73 that are engaged by a detent Y4: which is controlled by means of a rod 75 and a handle portion 76. The handle portion 76 57. The handle it is located lctween the quadrant T1 and the bearing member and is spaced from the latter by means of a washer 80, 2. When the detent H is raised of engagement with the notches in the quadrant 71, the handle 77 may be rotated with respect to shaft 56 and in this manner the arm 79 can be moved independently of the arm 5? so that the wheel that is attached to the arm 79 can be raised or lowered with respect to the wheel that is attached to arm 57. From the above description it will be apparent that the handle 65 can be employed for raising and lowering the two wheels simultaneously and an equal amount. lVhile the handle 77 can be employed for changing the relative position of the wheel.

Rods 81 and 82 have their 'rorward ends pivoted to the beam 1 by means of a bolt 88. The rear ends of these rods are forked and is each provided with tw spaced parallel bars 84 and 85 which straddle the wheel and which are provided with openings for the reception of the bolts 62. hese bars prevent the wheels from rotating about the pivot 58 when the plow is in operation. In order to prevent sidewise motion oi? the wheels the bars 81 and 82 extend through guide loops 86 in the manner shown in Fig.

height, but if the plow is to be used on a hillside one or the otl of the wheels is adjusted to a lower position so that the plow itself retains a substantially horizontal position. By means oi the lever 87 the point of the plow can be raised and lowered so as to facilitate transportation and so as to vary the depth of the ditch. A pull bar 88 has its rear end connected to the beam 1 by means of a bolt 83 and has its front end extending through the loop 89. A clevis 90 is pivotally attached to the front end of the pull bar and to this clevis the horses or the tractor are or is attached.

From the above description it will be apparent that I have provided an improved construction of ditching plow by means of which it is possible to adjust the parts so as to conform with the inclination of the land and by means of which the depths of the ditch can be easily regulated.
